This time, the tables were turned. When Leo Brown, a theology teacher at St. Thomas Aquinas High School in Overland Park, left the school to serve as a first sergeant in Afghanistan, the students and faculty surprised him with a big send-off. On Oct. 31, it was Brown’s turn to surprise everyone with his return to Aquinas. The returning airman greeted everyone soon after school started at a surprise assembly. He has spent the intervening time on deployment with the U.S. Air Force Reserve’s 442nd Fighter Wing Maintenance Group.
